[Modification of food and water intake after experimental duodenal occlusion in the sheep]

A duodenal occlusion was performed near the pylorus in 10 sheep fed hay ad libitum and barley (350 g/day). The first day, grain intake ceased and a 60% decrease in forage and water intake occurred. Hay intake approached zero on day 4, but some water intake persisted, probably because of the continuation of diuresis.
